NAME

       s3qlctrl - Control a mounted S3QL file system

SYNOPSIS

          s3qlctrl [options] <action> <mountpoint> ...

       where action may be either of flushcache, upload-meta, cachesize or log-metadata.

DESCRIPTION

       S3QL  is  a  file  system  for  online  data  storage.  Before  using S3QL, make sure to consult the full
       documentation (rather than just the man  pages  which  only  briefly  document  the  available  userspace
       commands).

       The s3qlctrl command performs various actions on the S3QL file system mounted in mountpoint.

       s3qlctrl  can only be called by the user that mounted the file system and (if the file system was mounted
       with --allow-other or --allow-root) the root user.

       The following actions may be specified:

       flushcache
              Uploads all changed file data to the backend.

       upload-meta
              Upload metadata to the backend. All file system operations will block  while  a  snapshot  of  the
              metadata is prepared for upload.

       cachesize
              Changes  the  cache  size  of  the  file  system. This action requires an additional argument that
              specifies the new cache size in KiB, so the complete command line is:

                 s3qlctrl [options] cachesize <mountpoint> <new-cache-size>

       log    Change the amount of information that is logged into ~/.s3ql/mount.log file. The  complete  syntax
              is:

                 s3qlctrl [options] log <mountpoint> <level> [<module> [<module> ...]]

              here  level  is  the  desired  new log level and may be either of debug, info or warn. One or more
              module may only be specified with the debug level and allow to restrict the debug output  to  just
              the listed modules.

OPTIONS

       The s3qlctrl command also accepts the following options, no matter what specific action is being invoked:

          --debug-modules <modules>
                 Activate  debugging  output  from  specified modules (use commas to separate multiple modules).
                 Debug messages will be written to the target specified by the --log option.

          --debug
                 Activate debugging output from all S3QL modules. Debug messages will be written to  the  target
                 specified by the --log option.

          --quiet
                 be really quiet

          --version
                 just print program version and exit

       Hint:  run  s3qlctrl  <action>  --help to get help on the additional arguments that the different actions
       take.

EXIT CODES

       s3qlctrl may terminate with the following exit codes:

       0      Everything went well.

       1      An unexpected error occured. This may indicate a bug in the program.

       2      Invalid command line argument.
